12 Claims.

This invention relates to a flanged wall coping. The invention aims to provide, in a manneras hereinafter set forth, a coping designed primarily as a protecting means for the top of a parapet wall, but it is to be understood that a coping, in accordance with this invention is for employment in any connection for which it may be found applicable.

The invention further aims to provide, in a manner as hereinafter set forth, a coping for the purpose referred to including a pair of internal pads for seating on and so formed for the reception of cementitious material for looking or securing them to the top of the wall.

The invention further aims to provide, in a manner as hereinafter set forth, a coping for the purpose referred to including a plurality of complemental units disposed in endwise aligned arrangement, and with the units having means for overlapping and interlocking to couple them together in the manner aforesaid.

The invention further aims to provide, in a manner as hereinafter set forth, a coping unit including a high end portion having its inner face formed throughout with a key, and a low end portion having its outer face formed throughout with a key receiving channel.

The invention further aims to provide, in a manner as hereinafter set forth, a coping unit including a body part of arcuate cross section, side flanges depending from said body part and spaced parallel depending lengtltwise grooved seating pads on the inner face of said body having their seating faces aligned with the upper end .of the inner faces of the flanges.

The invention further aims to provide, in a manner as hereinafter set forth, a flanged coping unit having spaced parallel depending portions on its inner face each formed lengthwise thereof with a substantially dovetailed groove in proximity to a side of the unit for the reception of cementitious material for securing the unit in v overlapping relation with respect to the top of a parapet wall.

The invention further aims to provide, in a manneras hereinafter set forth, a double flanged coping formed of a plurality of complemental overlapping interengaging units forming a smooth surface on the outside of the wall with which the coping is correlated; each unit including spaced internal pads for seating it on the wall and an internal key inwardly of one end and spaced from one end of the pads, each unit having its pads formed with grooves for the reception of cement to secure the pads on the wall, and each unit being provided with a peripheral groove at its other end running the full length of the lap as well as down a flange for coaction with a key of an adjacent unit to not only anchor the units at the lap, but to alsotake care of any leakage that might seep through the joints between the units.

The invention further aims to provide, in a manner as hereinafter set forth, a coping which is simple in its construction, durable, strong, readily assembled in relation to a parapet wall, thoroughly efficient in its use, substantially nonleakable, and comparatively inexpensive to manufacture.

Embodying the aims aforesaid and others which may hereinafter appear, the invention consists of the novel construction, combination and arrangement of parts as will be more specifically described and illustrated in the accompanying drawings, wherein is shown the preferred embodiment of the invention, but it is to be understood that changes, variations and modifications may be resorted to which fall within the scope of the invention as claimed.

In the drawings:

Figure 1 is a fragmentary view in side elevation of a coping in accordance with this invention, installed with respect to a parapet wall,

Figure 2 is a section on line 2-2 Figure 1,

Figure 3 is a view looking towards one end of a coping unit.

Figure 4 is a view similar to Figure 3 looking towards the other end of the unit,

Figure 5 is a fragmentary view in longitudinal section of the coping, and

Figure 6 is a fragmentary bottom plan of a unit.

The flanged wall coping will consist .of a plurality of overlapping interengaging complemental units preferably constructed from clay, but it is to be understood that the units maybe formed from any suitable material.

With reference to the drawings, l indicates a parapet wall and 2 the top of the latter. 3 indicates generally the flanged coping arranged relatively to the top and sides of wall I. The units of the coping 3 are of like form and designated 4. Each unit 4 consists of a body part 5 of arcuate contour in transverse cross section formed of a high portion 6 and a low portion 7 of materially less height, length and Width than the portion 6 (Figure 5). The top of portion 1 is arranged below the top of portion 6 to thereby provide a shoulder 8 and a seat 9. The shoulder 8 is positioned inwardly of an end of body the bottom of the other side of said part.

said portions are connected together. Depending from the sides of the portion 6 is a pair of flanges I. Depending from the sides of the portion 7 is a pair of flanges l2 of less width than and which merge into the flanges H at the point of joinder of-the part Ill with portion 7. The bottom of the flanges H, 12, are flush with each other. As the flanges l2 are inset with respect to the flanges II, the outer' sides'of flanges I 2 form downward continuations of the shoulder 8.

The seat 9 from end. to end thereof is formed with a transverse semi-circulangroove. I3 and,

the outer side faces of the flanges l2 are pro Vided with downward continuations I 4 of the groove I 3. The inner face of the portion 6 in proximity to its end I5 is formed transversely with a depending continuous semi-circular key l6, and the inner faces of the flanges II are formed with depending continuations ll of the key I6.

Each unit includes a pair of spaced parallel depending pads l8, which areformed integral with the inner faces of the said portions 6, l. The pads l8 extend from a point inwardly of the end and key l6 of portion 6 to the free endof the portion 7. The pads l8 throughout are formed with dovetail grooves 9 opening centrally of the bottoms thereof. The pads are for seating on the top of wall I, and the flanges are for disposing at opposite sides of the wall.

When the coping is arranged relative to the wall I, the pads I8 are secured to the'latter by a body of cement 2D deposited on the top 2 of the wall I at each side of said top. The cement extends into the grooves 19 of the pads l8, engages the lower face of the pads, isf-orced by compression against the upper portion of the sides of the wall I (Figure 2) and extends into continuations M of the groove l3. When a unit of the coping is arranged relative to an adjacent unit the end l5 of a portion 6 of one unit overlaps the portion 1 of an adjacent unit, and the key and its continuations seat on the groovel3 of an adjacent unit, as well as the continuations M of such groove, whereby the units are not only overlapped, but are interengagedand locked together, the cement assisting for such purpose. When the units are disposed in overlapping relation the end l5 of the portion 6 of one unit abuts the shoulder 8 formed by an end of the portion 6 of an adjacent unit.

Each unit includes what maybe termed a onepiece body formed of a pair of inverted U-shaped parts; one of greater length, width and height than the other. Each of said parts includes what may be termed a bight and a pair of. arms. The part of smallest length having its outer face inset throughout with respect to the outer face of the other of said parts, thereby forming said body with a peripheral shoulder'between its transverse median and one end. The part of greatest height being formed on its inner face in proximity to one end of said body with a continuous key extending from the bottom of one side of such part to The part of smallest height has its outer face formed with a continuous groove extending from the bottom of one side of such part to the bottom of theother side of such part. Eachunit further includes a pair of grooved parallel spacedpadson the inner face of its one-piecebody extending part 5 and is disposed upwardly at right angles to the seat 9. That end of the portion 5 which provides the shoulder 8 has a depending part II] which merges into the portion 1 whereby the from a point removed from one end of said body to the other end thereof.
